Some such sequestered place the poet of “Sir Galahad, a Christmas Mystery,” may have had in mind when he pictured the lonely knight struck with awe by hearing a voice which said that the great Quest would be achieved by him alone-- “Following That holy Vision, Galahad, go on.” To this very spot, too, if legend be true, the knights who had failed returned. The story of the Holy Grail is too profound and complex a study to be treated in these pages save in the most superficial and limited manner. Volumes have been and still can be devoted to the subject, and yet not exhaust all that is to be told of this world-legend with its infinite variations and its numberless phases and meanings. Like a river of many obscure sources, most of which are now partly known, thanks to the perseverance of the most devoted and painstaking of exploring scholars, it gathers in volume upon the way, and to trace it backward or onward involves an equally long and tortuous journey. The primary form of the legend, the actual beginning of the Grail romance cycle, remains a mystery and seemingly undiscoverable. The oldest poems on the subject, those of Christien de Troyes and Robert de Borron, were founded upon a model, or models, absolutely untraced. That it was a primitive Celtic tradition admits of no doubt, but when Walter Map incorporated the legend into the Arthurian story in the thirteenth century there were Latin, German, and French originals for him to work upon. In one chief version of the narrative Perceval is the supreme figure; in the other Galahad, Perceval, and Bors all achieve a measure of success, the first named being the absolute victor and the others being admitted to partial triumph. The Christian element in the cycle is distinct almost throughout, and the many versions have one point in common--the sanctity of the Grail, its connection with the Saviour, or with John the Baptist, and its continued miraculous power proceeding from this connection. But the Celtic originals would be free from traces of Christian symbolism. In Malory we find the Holy Vessel in the possession of King Pelleas, nigh cousin to Joseph. When the king and Sir Lancelot went to take their repast a dove entered the window of the castle, and she bore in her bill a little censer of gold from which proceeded a savour as if all the spicery of the world had been there. The table was forthwith filled with good meats and drinks by means of the Grail, “the richest thing that any man hath living,” as King Pelleas declared. Whether the Grail was a chalice which received the blood of the crucified Lord; whether, as others have affirmed, it was the dish on which the head of John the Baptist had lain; or whether it was a miraculous stone which fell from the crown of the revolting angels made for Lucifer, the belief in its reality in early times must have been sincere and ineradicable. It was said to have sustained
